Philodendron scandens ssp. oxycardium - Heart-leaf Philodendron

Philodendron scandens Heart-leaf Philodendron

Philodendron scandens ssp. oxycardium or Heart-leaf Philodendron is an evergreen perennial vine native to Tropical America. It is one of the easiest and most common of the Philodendrons grown today. Most of the time the plants are sold as Cordatum Philodendron or Cordatum Ivy. The dark green, heart-shaped leaves are usually up to 5 inches (12.7 cm) long on juvenile plants and can be up to 12 inches (30 cm) long on mature plants. They are very vigorous growers that can take a wide range of conditions.

Blooming: The flowers can appear at any time of the year, although most plants in captivity never bloom. The greenish spathes are about 6 inches (15 cm) long. They are not particularly showy.

Culture: Philodendron scandens ssp. oxycardium will live in a wide range of conditions from full sun to full shade with a moist well-drained soil mix. In the greenhouse, we use a soil mix that consists of 2 parts peat moss to 1 part loam to 1 part sand or perlite. The plants are well watered and allowed to dry slightly before watering again. They are fertilized monthly with a balanced fertilizer diluted to ½ the strength recommended on the label. They are very vigorous growers and should be re-potted on a yearly basis when the plants are young. As the plants mature, they need to be re-potted every couple of years. During the winter months, water should be restricted to about half of what you give them during the growing season. Fertilizer should not be used during this period.

Propagation: Philodendron scandens ssp. oxycardium are easily propagated from cutting or layers.

Philodendron scandens ssp. oxycardium was featured as Plant of the Week November 11-17, 2005.
